Treatments consisted of 20% DDGS or 20% Hemp (DM basis) in a finishing ration.

Performance measures were analyzed over the 111-d feeding period.

Marbling score: 400 = Slight⁰⁰, 450 = Slight⁵⁰, 500 = Small, etc.

Yield grade (YG) = 2.50 + (0.9843 × rib fat thickness, cm) + (0.2 × 2.5% kidney, pelvic, and heart fat) + (0.0084 × hot carcass weight) − (0.496 × LM area, cm²; USDA, 2017).
